Abstract A method for the quantitative determination of γ'-phase has been developed by direct weighing after all the matrix γ-phase of a thin foil specimen less than 0.1mm thick is dissolved by a long time potentiostatic electrolysis. The difficulty of the conventional analytical method by means of electrolyte extraction, which is caused by aggregation and growth of network γ'-phase in Ni-base superalloy containing high Al and Ti on long exposure to high temperature, has been overcome. The results obtained by this method are in agreement with that by ordinary isolation one.
